1999 – 2000 – Body Control Module 9366801 Programmed To Your VIN

1999 – 2000 GM Vehicles Body Control Module (BCM) 9366801 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with erratic door locks or dashboard lights flickering unpredictably in your late ’90s Chevy Silverado? You’re not alone—I’ve seen countless truck owners pull into the shop frustrated by these gremlins, often tracing back to a failing Body Control Module. Questions like “Why won’t my 1999 GMC Sierra power windows respond?” or “How do I fix intermittent electrical issues in my 2000 Chevy Blazer?” flood forums, pointing to BCM glitches. This pre-programmed BCM, featuring the core part number 9366801 and cross-compatible with 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, 8191536250, and 09366801, arrives ready for your VIN-specific flash with the latest GM updates. It restores seamless control over body functions, from lighting to security systems, drawing on my two decades of diagnostics to confirm it’s a direct, reliable solution that prevents recurring faults.

Common Issues & How This Fixes Them

In my experience troubleshooting 1999-2000 GM trucks, BCM failures often manifest as mysterious electrical woes. For instance, you might notice power door locks failing to engage, a symptom tied to degraded internal circuits from years of vibration and moisture exposure. This leads to frustrating scenarios where your Sierra 1500 won’t secure properly, increasing theft risks. Another common headache? Intermittent interior lights or wipers activating on their own—caused by corrupted software in the module, which disrupts signal processing. I’ve diagnosed cases in Blazer models where this escalated to battery drain, leaving owners stranded. Replacing with this VIN-programmed BCM resolves these by refreshing the control logic, restoring precise command execution. Consider the “no-start due to security light” issue in Silverado pickups; it’s often a BCM communication breakdown with the theft deterrent system. This unit’s updated flashes eliminate that, based on real shop fixes I’ve performed. Additionally, airbag warning lights may persist post-swap without proper reset, but following targeted procedures ensures safety features align perfectly. Overall, it tackles root causes like worn capacitors, preventing cascading failures in connected systems.

Easy Installation Guide

1. Gather tools: You’ll need a socket set, trim removal tools, and your vehicle’s VIN—safety first, disconnect the battery to avoid shorts.
2. Locate the BCM: In most models like the Sierra or Silverado, it’s under the left dash; for S10 or Blazer, check center dash—refer to your manual for exact positioning.
3. Remove the old unit: Unplug connectors carefully, unbolt the module, and note any ID labels for verification against compatibles like 16257125.
4. Install the new BCM: Secure it in place, reconnect harnesses, and reconnect the battery—double-check for firm connections to prevent signal errors.
5. Perform relearn procedures: If no-start occurs, initiate theft deterrent relearn by cycling the key from off to run (without cranking) three times for 10 minutes each, allowing the system to sync. For airbag light reset, use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ process.
6. Calibrate as needed: Some vehicles require brake pedal recalibration for optimal safety—consult a pro if unsure, as steps vary by model like the Astro or Safari.
